3 Claims. 1

The present invention relates to new and useful improvements in sawsets, and more particularly to a device of this character adapted forsetting the teeth of chain saws and embodying means for setting theteeth at opposite sides of the saw.

The invention is designed particularly for use in the setting of theteeth of a chain saw while the saw is clamped in position on asaw-filing bench, and the invention embodies the provision of an anviladapted for positioning at either side of the saw and hammers adaptedfor use at the respective sides of the saw and adapted upon delivery ofan impact to the hammers to set the teeth at a desired angle.

A further object of the invention is to provide a device of thischaracter of simple and practical construction, which is efiicient andreliable in use, relatively inexpensive to manufacture, strong anddurable, and otherwise well adapted for the purposes for which the sameis intended.

Other objects and advantages reside in the details of construction andoperation, as more fully hereinafter described and claimed, referencebeing had to the accompanying drawing forming part hereof, wherein likenumerals refer to like parts throughout, and in which:

Figure 1 is a front elevational view with parts broken away and shown insection.

Figure 2 is a side elevational view.

Figure 3 is a sectional view taken substantially on a line 33 of Figure1.

Referring now to the drawing in detail, wherein for the purpose ofillustration I have disclosed a preferred embodiment of the invention,the numeral 5 designates an anvil having one end formed with oppositelyinclined striking faces 6 and I and having its opposite end tapered toform a handle 8 by means of which the striking faces of the anvil may beheld against the side of a chain saw 9 while the saw is held with itsupper flight secured in a stationary position by means of a clampingplate I of a saw-filing bench.

The lower portion of the anvil is of a straight construction, asindicated at II in Figure 3 of the drawing, for bearing in confrontingrelation against the base of the teeth 9 of the saw, and the straightlower surface I I of the anvil is formed with a horizontally extendinggroove I2 adapted to accommodate the rivets I3 used for pivotallyconnecting the teeth of the saw while the anvil is slidably movedagainst one side of the saw.

Upper and lower bolts I4 and I5 extend transthe hammer I9.

versely of the anvil 5 and a pair of upwardly and forwardly curved armsI6 are provided with slots I1 in their loweri portions for receiving theends of the bolts for vertically adjusting the arms at opposite sides ofthe anvil.

A bolt I8 extends transversely at the upper ends of the arms I6 andconstitutes a shaft supported between the upper ends of the arms and onwhich a pair of hammers I9 and 20 are swingably mounted by hangers 2|and 22 projecting upwardly from the hammers. The hammers are secured inspaced relation on the bolt I8 by means of spacing washers 23.

The striking face 24 of the hammer I9 is inclined in the plane of theinclined face 6 of the anvil, while the striking face 25 of the hammer20 is inclined in the plane of the face I of the anvil, as will beapparent from an inspection of Figure 3 of the drawing.

In the operation of the device, the lower front edge of the anvil 5 ispositioned on the upper edge of the clamping plate In at one side of thechain 9 and with the inclined face 6 of the anvil bearing against oneside of the teeth of the chain. A hammer blow is then struck against thehammer I9 whereby to set the teeth of the saw in accordance with theinclination of the face 6 of the anvil and the striking face 24 of Thedevice is moved along the side of the saw for setting the alternateteeth by the hammer I9 and the device is then positioned at the oppositeside of the saw and the remaining teeth set by the hammer 20 andinclined face I of the anvil.

It is believed that the details of construction, manner of use andadvantages of the device will be readily understood from the foregoingwithout further detailed explanation.

It is to be understood, however, that even though I have herein shownand described a preferred embodiment of my invention, the same issusceptible of certain changes fully comprebended by the spirit of theinvention as herein described, and the scope of the appended claims.

Having thus described the invention, what I claim is:

1. A saw set comprising an anvil adapted for holding against either sideof a saw and having oppositely inclined anvil faces for oppositelysetting the teeth at the respective sides of a saw, a pair of armsrising from the anvil in spaced relation to each other, a shaftsupported at the upper ends of the arms, and a pair of hammersswinga-bly mounted on said shaft for striking the teeth of the saw, saidhammers having striking faces inclined in the plane of the respectiveanvil faces.

2. A saw set comprising an anvil adapted for holding against either sideof a saw and having oppositely incline-d anvil faces for oppositelysetting the teeth at the respective sides of a saw, a pair of armsrising from the anvil in spaced relation to each other, means forsecuring the arms in vertically adjusted position on the anvil, a shaftsupported at the upper ends of the arms, and a pair of hammers swingablymounted on said shaft for striking the teeth of the saw, said hammershaving striking faces inclined in the plane of the respective anvilfaces.

3. A saw set comprising an anvil including a handle for holding theanvil against either side of a saw, said anvil having a straighttransverse lower front portion and oppositely inclined upper frontportions for oppositely setting the teeth at the respective sides of asaw, a pair of upwardly and forwardly extending arms secured at theopposite sides of the anvil, a shaft supported at the upper ends of thearms, and a pair of hammers swingably mounted on said shaft for strikingthe sides of the teeth of the saw, said hammers having striking facesinclined in the plane of the respective anvil faces.
